CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application Ser. No. 62/984,853 filed Mar. 4, 2020, which is incorporated herein in its entirety.

TECHNICAL FIELD

The present disclosure generally relates to the display of extended reality (XR) environments, and in particular, to techniques for presenting views of XR environments comprising visual representations of multiple applications.

BACKGROUND

Various devices are used to provide users with XR environments. The content of such XR environments may be experienced by a user using a mobile device, head-mounted device (“HMD”), or other device that presents the visual or audio features of the content. The experience can be, but need not be, immersive, e.g., providing most or all of the visual or audio content experienced by the user. The content can include pass-through video (e.g., in which real-world content is captured by a camera and displayed on a display with additional content) or optical-see-through (e.g., in which real-world content is viewed directly or through glass and supplemented with displayed additional content).

In some instances, the content can also include visual representations of multiple applications. Some devices and software programs facilitate the display of such content that includes visual representations of multiple applications. However, these devices and software programs do not provide sufficient features for resolving any conflicts arising among the multiple applications concerning views of XR environments.

DESCRIPTION

Numerous details are described in order to provide a thorough understanding of the example implementations shown in the drawings. However, the drawings merely show some example aspects of the present disclosure and are therefore not to be considered limiting. Those of ordinary skill in the art will appreciate that other effective aspects or variants do not include all of the specific details described herein. Moreover, well-known systems, methods, components, devices and circuits have not been described in exhaustive detail so as not to obscure more pertinent aspects of the example implementations described herein.

Referring to FIG. 1, an example operating environment 100 for implementing aspects of the present disclosure is illustrated and designated generally 100. In general, operating environment 100 illustrates an electronic device 120 involved in the display of two-dimensional (2-D) content or three-dimensional (3-D) content, including but not limited to, an extended reality (XR) environment to a user. an extended reality (XR) environment refers to a wholly or partially simulated environment that people sense and/or interact with via an electronic device. For example, the XR environment may include augmented reality (AR) content, mixed reality (MR) content, virtual reality (VR) content, and/or the like. With an XR system, a subset of a person's physical motions, or representations thereof, are tracked, and, in response, one or more characteristics of one or more virtual objects simulated in the XR environment are adjusted in a manner that comports with at least one law of physics. As one example, the XR system may detect rotational head movement and, in response, adjust graphical content and an acoustic field presented to the person in a manner similar to how such views and sounds would change in a physical environment. As another example, the XR system may detect rotational or translational movement of the electronic device presenting the XR environment (e.g., a mobile phone, a tablet, a laptop, or the like) and, in response, adjust graphical content and an acoustic field presented to the person in a manner similar to how such views and sounds would change in a physical environment. In some situations (e.g., for accessibility reasons), adjustments to characteristic(s) of graphical content in an XR environment may be made in response to representations of physical motions (e.g., vocal commands).

There are many different types of electronic systems that enable a person to sense and/or interact with various XR environments. Examples include head mountable systems, projection-based systems, heads-up displays (HUDs), vehicle windshields having integrated display capability, windows having integrated display capability, displays formed as lenses designed to be placed on a person's eyes (e.g., similar to contact lenses), headphones/earphones, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablets, and desktop/laptop computers. A head mountable system may have one or more speaker(s) and an integrated opaque display. Alternatively, a head mountable system may be configured to accept an external opaque display (e.g., a smartphone). The head mountable system may incorporate one or more imaging sensors to capture images or video of the physical environment, and/or one or more microphones to capture audio of the physical environment. Rather than an opaque display, a head mountable system may have a transparent or translucent display. The transparent or translucent display may have a medium through which light representative of images is directed to a person's eyes. The display may utilize digital light projection, OLEDs, LEDs, uLEDs, liquid crystal on silicon, laser scanning light source, or any combination of these technologies. The medium may be an optical waveguide, a hologram medium, an optical combiner, an optical reflector, or any combination thereof. In some implementations, the transparent or translucent display may be configured to become opaque selectively. Projection-based systems may employ retinal projection technology that projects graphical images onto a person's retina. Projection systems also may be configured to project virtual objects into the physical environment, for example, as a hologram or on a physical surface.

In some implementations, the electronic device 120 is a handheld electronic device (e.g., a smartphone or a tablet) configured to present content representing a view (e.g., view 200 of FIG. 2) of an XR environment to a user. In some implementations, the electronic device 120 is a head-mounted device (HMD) that a user wears. Such an HMD may enclose the field-of-view of the user. In some implementations, an HMD is worn is a way that one or more screens are positioned to display content representing a view of an XR environment in the field-of-view of the user.

In some implementations, electronic device 120 is configured to interact with a controller (not shown) separate from electronic device 120 to present content representing a view of an XR environment to a user. In some implementations, the controller includes a suitable combination of software, firmware, or hardware to facilitate presentation of content representing a view of an XR environment to a user. In some implementations, the controller is a computing device communicatively coupled to electronic device that is local or remote relative to a physical environment (e.g., scene 110) proximate to electronic device 120. In one example, the controller is a local server located within a physical environment proximate to electronic device 120. In another example, the controller is a remote server (e.g., a cloud server, central server, etc.) located outside of the physical environment proximate to electronic device 120. In some implementations, the controller is communicatively coupled with the electronic device 120 via one or more wired or wireless communication channels (e.g., BLUETOOTH, IEEE 802.11x, IEEE 802.16x, IEEE 802.3x, etc.).

FIG. 2 is an example of presenting content 200 representing an XR environment on a display (e.g., the one or more displays 1006 of FIG. 10) of electronic device 120. The XR environment represented by content 200 comprises depictions of physical elements within scene 110, such as a floor 112, a first wall 114, a second wall 116, and a table 130. Content 200 further comprises depictions of virtual elements corresponding to multiple applications, such as a representation 210 of a checkers application, a representation 220 of a media application, and a representation 230 of a weather application. Each representation depicted in FIG. 2 comprises computer-generated content associated with or provided by a different application among the multiple applications. For example, representation 210 comprises computer-generated content depicting a virtual checkers board associated with the checkers application and representation 230 comprises computer-generated content indicative of weather conditions provided by the weather application.

In one implementation, the XR environment represented by content 200 provides a “virtual desktop” comprising visual representations corresponding to multiple, separately executing applications. In this implementation, the virtual elements comprising those visual representations are positioned or configured in the XR environment such that they are perceived to coexist with physical elements (e.g., table 130) within the XR environment. For example, representation 210 and associated computer-generated content 212 depicting virtual checkers are positioned in the XR environment represented by content 200 such that those virtual elements are perceived as existing on a horizontal surface 132 of table 130.

Content 200 generally corresponds to a view of an XR environment that a user of electronic device 120 may perceive before electronic device 120 modifies an ambience of the XR environment, as described in greater detail below. “Ambience” generally refers to a character and/or atmosphere of an XR environment that a user perceiving the XR environment associates with the XR environment. Various factors contribute to such ambience. For example, reducing a brightness level associated with an XR environment may contribute to a user associating that environment with a relaxing atmosphere whereas increasing the brightness level may contribute to the user associating the XR environment with an energetic atmosphere. As another example, spatializing ambient sound for light rain all around a user in an XR environment may contribute to the user associating that environment with a relaxing atmosphere whereas spatializing ambient sound for smashing glass and collapsing structures may contribute to the user associating the XR environment with a threatening atmosphere.

In various implementations, an ambience unit (e.g., ambience unit 1042 of FIG. 10) facilitates customization of an ambience of an XR environment presented to a user. To that end, the ambience unit exposes one or more control parameters for modifying the ambience of the XR environment to multiple applications associated with or providing content corresponding to the XR environment. An application interface unit (e.g., application interface unit 1044) minimizes a likelihood that such control parameters receive conflicting inputs or commands by arbitrating control access to the one or more control parameters among the multiple applications.

One aspect of arbitrating control access involves the application interface unit designating a particular application among the multiple applications as an elevated application. In one implementation, designating a particular application as an elevated application comprises the application interface unit identifying the particular application based on one or more identification criterion. Such identification criterion may include: a default configuration, a priority setting, a user preference, a user input, a characteristic of the particular application, a current context of the XR environment, a current context of a physical environment proximate to electronic device 120, or a combination thereof.

Upon designating the particular application as the elevated application, the application interface unit provides the particular application with access to a control parameter configured to modify an ambience of the XR environment. While the particular application is designated as the elevated application, the application interface unit restricts or precludes other applications among the multiple applications from accessing the control parameter. For example, the application interface unit may provide the particular application with read-write access to the control parameter while providing the other applications with no access or read-only access to the control parameter. In one implementation, an elevated application is provided with exclusive access to the control parameter. In one implementation, any conflicts arising among the multiple applications related to the control parameter are resolved based on which particular application among the multiple applications is designated as the elevated application.

By providing an elevated application with access to a control parameter, the application interface unit enables the elevated application to interact with the ambience unit to change a value of the control parameter based on user input received via the elevated application. AN XR content creation unit (e.g., XR content creation unit 1046 of FIG. 10) detects changes to the value of the control parameter and modifies the ambience of the XR environment accordingly. As illustrated by comparing FIG. 2 with any of FIGS. 3-4, the control parameter to which the elevated application receives access may modify the ambience of the XR environment in various ways.

In one implementation, designating the particular application as the elevated application alters routing decisions of a user input detection process concerning user input among the multiple applications. For example, the application interface unit may designate a first application among the multiple applications as the elevated application. In this example, the user input detection process may route user input (e.g., gaze tracking data, selection gesture data, and the like) to a second application of the multiple applications prior to the first application being designated as the elevated application. However, subsequent to the first application being designated as the elevated application, the user input detection process may route such user input to the first application. In one implementation, the application interface unit comprises the user input detection process.

A comparison between FIGS. 2 and 3 illustrates an example in which the elevated application receives access to a control parameter that modifies the ambience of the XR environment by adjusting a lighting condition of the XR environment. In this example, the application interface unit may designate the media application associated with representation 220 as the elevated application while presenting content 200 of FIG. 2. Upon designating the media application as the elevated application, the application interface unit provides the media application with access to the control parameter that adjusts the lighting condition of the XR environment.

In FIG. 2, a value of the control parameter may define a first state in which the lighting condition of the XR environment comprises a maximum brightness level. User input received via the media application may change that value of the control parameter to a value that defines a second state in which the lighting condition of the XR environment comprises a minimum brightness level. Responsive to detecting that change to the value of the control parameter, the XR creation unit generates content 300 in which the lighting condition of the XR environment is adjusted to the second state.

A comparison between FIGS. 2 and 4 illustrates an example in which the elevated application receives access to a control parameter that modifies the ambience of the XR environment by adjusting an immersion level of the XR environment. In this example, the media application associated with representation 220 is again designated by the application interface unit as the elevated application while presenting content 200 of FIG. 2. Upon designating the media application as the elevated application, the application interface unit provides the media application with access to the control parameter that adjusts the immersion level of the XR environment.

In FIG. 2, a value of the control parameter may define a first inversion level in which a user may equally perceive both physical elements and virtual elements in the XR environment. User input received via the media application may change that value of the control parameter to a value that defines a second inversion level in which the user's ability to perceive virtual elements is reduced. Responsive to detecting that change to the value of the control parameter, the XR creation unit generates content 400 in which the immersion level of the XR environment is adjusted to the second immersion level. In content 400, the user's ability to perceive a representation 430 of the weather application is reduced relative to its representation 230 in content 200 while the user's ability to perceive depictions of physical elements (e.g., table 130) remains static. Other virtual elements of content 400, such as a representation 410 of the checkers application, associated computer-generated content 412, and a representation 420 of the media application are also less perceivable than their counterparts in content 200.

In the examples discussed above with respect to FIGS. 3 and 4, the application interface unit provides an elevated application with access to a control parameter that modifies aspects of the XR environment's ambience that generally pertain to the XR environment at large. The ambience of the XR environment that such control parameters modify may be referenced as “environmental ambience”. In some implementations, the ambience unit exposes one or more user interface parameters that modify aspects of the XR environment's ambience that are more localized to a particular application among the multiple applications. The ambience of the XR environment that such user interface parameters modify may be referenced as “local ambience”. Each user interface parameter is configured to modify a local ambience pertaining to portions of the XR environment occupied by a visual representation of the particular application or portions of the XR environment within a predefined proximity to that representation.

By way of example, the application interface unit may provide the weather application, as an elevated application, with access to a control parameter corresponding to an environmental audio ambience. In this example, the weather application may modify the control parameter to spatialize weather-related ambient sound (e.g., rainfall) all around a user in an XR environment. In an implementation, one or more non-elevated applications (e.g., the media application) may each spatialize audio from a respective direction of a corresponding representation concurrent with a modification of a control parameter corresponding to an environmental audio ambience.

As another example, the application interface unit may provide the weather application, as an active application, with access to a user interface parameter corresponding to a local audio ambience. In this example, the weather application may modify the user interface parameter to spatialize weather-related ambient sound (e.g., rainfall) from a direction of its corresponding representation in an XR environment. In an implementation, one or more non-active applications (e.g., the media application) may each spatialize audio from a respective direction of a corresponding representation concurrent with a modification of a user interface parameter corresponding to an local audio ambience.

In implementations with user interface parameters configured to modify local ambiences, another aspect of arbitrating control access involves the application interface unit designating a particular application among the multiple applications as an active application. In one implementation, the active application is identified by the application interface unit based on a detected location of a user position within the XR environment. In one implementation, the active application is identified by the application interface unit responsive to receiving user input that designates the particular application as the active application. In one implementation, the active application is identified by the application interface unit responsive to detecting an ongoing interaction between the particular application and a user.

Upon designating the particular application as the active application, the application interface unit provides the particular application with access to a user interface parameter configured to modify a local ambience of the XR environment. While the particular application is designated as the active application, the application interface unit precludes other applications among the multiple applications from accessing the user interface parameter. For example, the application interface unit may provide the particular application with read-write access to the user interface parameter while providing the other applications with no access or read-only access to the user interface parameter. In one implementation, an active application is provided with exclusive access to the user interface parameter.

In one implementation, designating the particular application as the active application alters routing decisions of a user input detection process concerning user input among the multiple applications. For example, the application interface unit may designate a first application among the multiple applications as the active application. In this example, the user input detection process may route user input (e.g., gaze tracking data, selection gesture data, and the like) to a second application of the multiple applications prior to the first application being designated as the active application. However, subsequent to the first application being designated as the active application, the user input detection process may route such user input to the first application. In one implementation, the application interface unit comprises the user input detection process.

A comparison between FIGS. 2 and 5 illustrates an example in which an active application receives access to a user interface parameter that modifies a local ambience of the XR environment. In this example, the weather application associated with representation 230 is designated by the application interface unit as the active application while presenting content 200 of FIG. 2. Upon designating the weather application as the active application, the application interface unit provides the weather application with access to the user interface parameter that modifies the local ambience of the XR environment.

In FIG. 2, a value of the user interface parameter may define a first state in which the lighting condition of representation 230 comprises a maximum brightness level. User input received via the weather application may change that value of the user interface parameter to a value that defines a second state in which the lighting condition of representation 230 comprises a minimum brightness level. Responsive to detecting that change to the value of the user interface parameter, the XR creation unit generates content 500 in which the lighting condition of that representation of the weather application is adjusted to the second state, as illustrated by representation 530. Of note, the local ambience of the XR environment in the example of FIG. 5 is modified without modifying the environmental ambience of the XR environment.

A comparison between FIGS. 5 and 6 illustrates an example in which an active application receives access to a user interface parameter that is configured to modify a local ambience of the XR environment based on a functionality provided by the active application. In this example, the application interface unit provides the weather application with access to the user interface parameter that modifies the local ambience of the XR environment based on the functionality provided by the active application. While presenting content 500 of FIG. 5, the weather application receives weather data indicative of a weather forecast change. In accordance with a functionality provided by the weather application, its representation is updated to reflect the weather forecast change, as illustrated by representation 630.

In FIG. 5, a value of the user interface parameter may define a first state in which a portion of the XR environment within a predefined distance of representation 530 is populated with image data depicting scene 110. In an implementation, the image data depicting scene 110 is obtained using an image sensor (e.g., an image sensor within the image sensory system 1012 of FIG. 10) of electronic device 120. In FIG. 6, user input received via the weather application may change that value of the user interface parameter to a value that defines a second state in which the portion of the XR environment within that predefined distance is populated with computer-generated content corresponding to the functionality provided by the weather application. Responsive to detecting that change to the value of the control parameter, the XR creation unit generates computer-generated content 632.

A comparison between FIGS. 6 and 7 illustrates an example in which a particular application among multiple applications may concurrently be designated as an active application and an elevated application. In this example, the weather application associated with representation 630 is again designated by the application interface unit as the active application while presenting content 600 of FIG. 6. Moreover, this example presumes that the media application associated with representation 220 remains designated as the elevated application, as discussed above with reference to FIG. 2. While presenting content 600, the application interface unit may designate the weather application as both the active application and the elevated application. For example, the application interface unit may reevaluate the one or more identification criterion discussed above with reference to FIG. 2 and designate the weather application as the elevated application responsive to that reevaluation.

Upon designating the weather application as the elevated application, the application interface unit provides the weather application with access to the control parameter that adjusts the lighting condition of the XR environment. In one implementation, the application interface unit removes access to the control parameter by the media application while the weather application is designated as the elevated application. In this example, the application interface unit provides the weather application with access to a control parameter configured to modify an appearance of one or more portions of the XR environment upon designating the weather application as the elevated application. In one implementation, other applications (e.g., the media application and the chess application) are precluded or restricted from modifying the one or more portions of the XR environment while the weather application is designated as the elevated application.

In FIG. 6, a value of the control parameter configured to modify the appearance of the one or more portions of the XR environment may define a first state in which that portion is populated with image data depicting scene 110. In an implementation, the image data depicting scene 110 is obtained using an image sensor (e.g., an image sensor within the image sensory system 1012 of FIG. 10) of electronic device 120. In FIG. 7, user input received via the weather application may change that value of the control parameter to a value that defines a second state in which that portion of the XR environment is populated with computer-generated content. In one implementation, the computer-generated content corresponds to a functionality provided by the elevated application. Responsive to detecting that change to the value of the control parameter, the XR creation unit generates computer-generated content 712, 714, and 716.

In one implementation, user input received via a particular application among multiple applications concurrently designated as an active application and an elevated application may modify both a local ambience associated with the particular application and an environmental ambience. For example, the user input discussed above with respect to FIG. 7 that updates the value of the control parameter may also update the value of the user interface parameter discussed above with respect to FIG. 6. In this instance, responsive to detecting that change to the respective values of the control parameter and the user interface parameter, the XR creation unit may also generate computer-generated content 632 and overlay representation 630 in content 700 with computer-generated content 632. As a result, that user input may modify both a local ambience associated with the weather application and an environmental ambience of the XR environment represented by content 700.

A comparison between FIGS. 2 and 8 illustrates an example in which a particular application designated as an active application is provided with supplementary access to another application. In this example, the weather application associated with representation 230 is designated by the application interface unit as the active application while presenting content 200 of FIG. 2. Upon designating the weather application as the active application, the application interface unit provides the weather application with supplementary access to another application. For example, the application interface unit may direct user input received via the weather application to an application programming interface (API) of a reference application, such as a search application.

In FIG. 2, user input indicative of a search query concerning an extended weather forecast may be received via the weather application while presenting content 200. Responsive to detecting the user input, the application interface unit may direct the user input to the API of the reference application. Upon receiving the user input at the API, the reference application may transition from an unlaunched state to a launched state and direct the search query to a search engine associated with the reference application. When the reference application receives a corresponding search response, the XR creation unit generates content 800, in which a representation 810 of the reference application is populated with data obtained in the corresponding search response.

FIG. 9 is a flowchart illustrating an exemplary method 900 of providing a view of an XR environment, according to some implementations. In some implementations, the method 900 is performed by a device (e.g., electronic device 120 of FIG. 1). The method 900 may be performed at a mobile device, HMD, desktop, laptop, server device, or by multiple devices in communication with one another. In some implementations, the method 900 is performed by processing logic, including hardware, firmware, software, or a combination thereof. In some implementations, the method 900 is performed by a processor executing code stored in a non-transitory computer-readable medium (e.g., a memory).

At block 902, the method 900 includes presenting, at an electronic device, content representing a view of an XR environment on a display of the electronic device. The XR environment comprising visual representations corresponding to a plurality of applications. At block 904, the method 900 includes designating a first application among the plurality of applications as an elevated application. In one implementation, designating the first application as the elevated application comprises identifying the first application based on a default configuration, a priority setting, a user preference, a user input, a characteristic of the first application, a current context of the XR environment, a current context of a physical environment proximate to the electronic device, or a combination thereof. In one implementation, designating the first application as the elevated application alters routing decisions of a user input detection process among the plurality of applications.

At block 906, the method 900 includes providing the elevated application with access to a control parameter configured to modify an ambience of the XR environment. In one implementation, the control parameter is configured to modify the ambience by adjusting a lighting condition of the XR environment from a first state to a second state. In one implementation, the control parameter is configured to modify an appearance of a portion of the XR environment. In one implementation, other applications among the plurality of applications are precluded from modifying the appearance of the portion of the XR environment while the first application is designated as the elevated application. In one implementation, the control parameter is configured to modify the ambience by adjusting an immersion level of the XR environment from a first level to a second level.

At block 908, the method 900 includes precluding other applications of the plurality of applications from accessing the control parameter while the first application is designated as the elevated application. In one implementation, the elevated application has exclusive access to the control parameter. In one implementation, any conflicts arising among the plurality of applications related to the control parameter are resolved based on which of the plurality of applications is designated as the elevated application.

In one implementation, method 900 further includes modifying the ambience of the XR environment based on user input received via the elevated application. In one implementation, method 900 further includes designating a second application among the plurality of applications as the elevated application. In one implementation, method 900 further includes providing the second application with access to the control parameter responsive to designating the second application as the elevated application. In one implementation, method 900 further includes removing access to the control parameter by the first application while the second application is designated as the elevated application.

In one implementation, method 900 further includes designating a third application among the plurality of applications as an active application. In one implementation, method 900 further includes providing the active application with access to a user interface parameter configured to modify a functionality provided by the active application. In one implementation, method 900 further includes precluding other applications of the plurality of applications from accessing the user interface parameter while the third application is designated as the active application. In one implementation, designating the third application as the active application alters routing decisions of a user input detection process among the plurality of applications. In one implementation, the active application is identified based on a detected location of a user position within the XR environment.

In one implementation, the ambience is an environmental ambiance and method 900 further comprises modifying a local ambience of a visual representation of the third application based on user input received via the third application without modifying the environmental ambience. In one implementation, method 900 further includes designating the third application as the elevated application and the method further comprises modifying both the local ambience of the visual representation of the third application and the environmental ambience based on user input received via the third application.
